What is "info"?

Might be a good idea to mention that it requires two libraries, BeautifulSoup and pygments. Also on line 20, you pass the format string an info variable which, from what I can see, isn't set.

Both content and new_content are excessive variables, especially content.

This is a good idea. But how am I supposed to use this feature? ie where does the content come from?
